Carbon Capture and Storage What is it and
Carbon Capture and Storage What is it and how can it help us?
Our world is warming up, and scientists say that people are polluting the Earth by burning fossil fuels. What can we do about it? First, let’s look at what an atmosphere is and why we need to capture and store carbon.
What is an atmosphere? Our Earth is surrounded by an atmosphere. It is made up of gases: mostly water vapour, some CO₂, methane, and nitrous oxide. The atmosphere acts like a blanket. It traps some heat, and lets some out. This keeps the Earth at a steady temperature of 15°C.
What is CO₂? CO₂ is natural in the atmosphere, and we need it in small amounts to keep our planet warm. BUT when people cut down trees, mine for metals and minerals, and burn fossil fuels; it adds too much CO₂ to the atmosphere. + + =

Scientists have found that the biggest cause of CO₂ increase is the burning of fossil fuels. Fossil fuels are things that we burn made from old plants and animals like gas and coal. This releases CO₂ into the atmosphere. The CO₂ gets stuck in the atmosphere, and it keeps some heat from escaping the Earth. This is how the Earth heats up. The carbon cycle is a natural process on Earth, but all the extra pollution is disrupting the cycle.

Matter Cycles Matter: anything that has mass and takes up space. • Unlike energy that flows through a food web never returning to the source (sun), matter does not leave the food web; it cycles. • As it cycles it changes from one form to another within the web. • In this manner, matter is used over and over again in a community. • Matter travels in cycles from the non-living (abiotic) environment into the living (biotic) food web and back to the non-living.
The Carbon Cycle
CARBON is an atom, or element, that is essential to life on Earth. Carbon can form a wide variety of molecules and substances from gases like carbon dioxide and methane (natural gas) to liquids like gasoline and vegetable oil to solids like wood or coal.
Carbon can be found in things such as: Soda Gasoline Vegetable Oil
The CARBON CYCLE is the movement of carbon through an ecosystem.
Why worry about global warming? We need to do something about global warming because an increased temperature in the world can have the following effects: More extreme weather like tornadoes and hurricanes Worsened smog causing higher rates of asthma Increased spread of disease Droughts
The Carbon cycle consists of different places and organisms which act as both sinks and sources. Sinks are places or organisms which take in and store carbon. Sources are places or organisms which release carbon.

How do we use fossil fuels? Using a computer Driving a car Heating homes Turning on lights
How much do we use fossil fuels? 65% of Saskatchewan’s electricity comes from coal. Saskpower says that there are over 300 years of coal reserves in Saskatchewan.
How much CO₂ do we make? Canada
What does that look like? In 2010, Canada produced 692 000 tonnes of CO₂. 1 tonne of CO₂ takes up 556. 2 m³. Canada’s surface area is 9 984 670 km² So…. . In 2010, Canadians produced a blanket of CO₂ that was 3. 86 cm thick over all of Canada!!!
What about Saskatchewan? Saskatchewan produced 72 100 000 tons of CO₂ in 2010. This is enough to build a skyscraper of CO₂ with a base the size of Taylor Field. That skyscraper would be over 4000 km high! The tallest building in Regina is the Delta Hotel, and it’s only 83. 8 m high! That’s a lot of CO₂!!!
Different sinks and sources include: - The ocean - Organic soil matter - The atmosphere - Marine sediments - Sedimentary rocks - Terrestrial plants - Fossil fuel deposits
A Natural Carbon Sink • • • Through the process of photosynthesis plants take up carbon dioxide gas and store the carbon it their tissues which is nearly 50% carbon by weight. Plants grow by taking carbon dioxide from the atmosphere and converting it into carbohydrates. Carbohydrates are then used as energy and material to build the cellulose and lignin which are the main constituents of plant tissue. This is called carbon sequestration. Look around the classroom, can you name 5 objects that store carbon?
Fast Facts 10 % of the world’s forest are found in Canada’s Boreal Forest covers 53% of Canada and 75% of all forests in Canada are boreal forests There are 993. 63 million acres of forest and other wood land in Canada Env. Canada
Carbon Storage Canadian Boreal Forest Boreal forests can store approximately 100 tonnes of carbon/ha (Australian National University). There are 500 million hectares of Boreal forest in Canada Therefore, the Canadian Boreal forest could potentially store 50 billions tons of carbon. But…
Forests-sinks and sources Forests are not only carbon sinks but sources as well. Carbon is lost to the atmosphere through cellular respiration, decomposition, and forest fires. Carbon Overload Canada produces nearly 700 000 tons of carbon dioxide equivalents per year (2010 data) The burning of fossil fuels is producing far too much carbon for our boreal forests to sequester CO 2 Atmospheric CO 2 Cellular Respiration Decomposition Forest Fires
Carbon Exchanges- Examining the Numbers Approximately 120 billion tons of carbon are sequestered each year in forests. There also releases of approximately 119 -120 billion tons of carbon in the same time period. We see that the end result is that by terrestrial exchanges trees sequester about 0 -1 billion tons of carbon each year. We must do more to stop the accumulation of carbon dioxide in our atmosphere Source California PDF
How Can We Help the Plants? One way that people can help the plants keep the air clean is by using Carbon Capture and Storage technology. This is a process that captures the CO₂ when cola is burned. It takes the CO₂ and pipes it deep underground so that it doesn’t pollute the air. We can also help the plants by turning off lights and appliances that we’re not using. When lights are on, there is coal burning somewhere, letting pollution into our air. So we should always turn things off when we’re not using them to save electricity and minimize pollution.

Now that we know how plants can’t sequester the CO 2 produced by burning fossil fuels, the real question is…
Is CO₂ a waste or a resource?
It must be a waste. . All of that CO₂ used to go up into our atmosphere and pollute our air… Coop Refinery http: //ccednet-rcdec. ca/en/node/11295 Boundary Dam www. agefotostock. com
How could it be a resource? Using CCS, we can take all that pollution, and turn it into something useful! Once the CO₂ is captured and liquefied, it can be sold to oil and gas companies. $$$ They inject the CO₂ into a well that still has oil or gas, but not enough pressure to pump it out. The CO₂ pushes out the last bits of oil and gas from the well.
What is CCS? CCS or Carbon Capture and Storage is when the CO₂ is captured after it is released when coal is burned. It is pressurized into liquid form. Then it gets piped deep underground.
CCS to the rescue!!! Many scientists say that Carbon Capture and Storage technology will be the best way to reduce large amounts of CO₂ emissions in the next 40 years.
How much can CCS help? The Saskpower Boundary Dam is being rebuilt with Carbon Capture and Storage technology. It will reduce emissions for that section of the facility by 90%. That’s the same as taking 250 000 cars off the road!!!

Where does the CO₂ go? It needs to go deep underground into a stable formation. It can’t be stored near the edges of plate tectonics. It sometimes get stored in old oil fields. It needs to be deep enough and sealed properly so that the CO₂ doesn’t escape.

CCS is an important part of the solution The IEA (International Energy Association) estimates that a 50% decrease in CO₂ emissions will still cause an increase of 2 - 3°C in global temperatures.
If we used CCS, the amount of CO₂ avoided would equal: Planting 62 000 trees and waiting 10 years for them to grow Cutting electricity emissions from 300 000 homes Environmental Protection Agency

An ecological footprint is a measure of human demand on the Earth’s ecosystems. lgmacweb. env. uea. ac. uk It represents the amount of biologically productive land sea area necessary to supply the resources a human population consumes and to absorb associated waste.
What does your Ecological Footprint tell you? It is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody followed a particular lifestyle. alexscolloquiumjournal. blogspot. com
Knowing your ecological footprint can help you learn how to conserve more and help protect ecosystems
